ABSTRACT:
Two pairs of opposing magnetic heads mounted in quadrature on a rotary drum simultaneously receive two independent video channels, one channel being quadrature-delayed with respect to the other. The heads simultaneously record the two video channels in adjacent tracks on a video tape moving at twice the normal linear tape speed. To playback one of the two simultaneously recorded video channels, the two pairs of heads retrace their respective recorded tracks while the video tape moves at twice normal linear speed, but only one opposing head pair is connected to playback circuitry. In an alternative embodiment, the tape moves at standard speed while the heads skip-field record the two quadrature-delayed video channels.
